IMPRVEMENT INDLIMPINSl APPARATUS.'l

, view, with portion of dnmper removed toshow the Bat. Figure 2is an "end view of our invention,showing the operating gear. l

Figure 3 is a vertical cross-section Figure 4 is a bottom view of one 'of the'dump'ers.

'Our invention hasrelation to means for ballasting and'iilling the Abeds of railways, and consists in the novel construction and combiationof devices intended for transporting gravel' upon and dumping it'from the ordinary transportation cars called iin-ts'.

A of the drawing represents the top of au ordinary flat, to which our apparatus isattaohed by means of bolts that are passed through the end pieces B B. '.lhev letter O represents 'a carrying and' dumpingbox, constructed with 'open top and front, as shown,

.and having aiixed to the outer sdeof each end a ratchet-bar, 1),# curved in the manner represented on figs. 2 and 3.

The letter a represents a series of rollers arranged upon' the bottom ofthe box 0, between slats h, in the mannershown'on fig. 1; and the letter v represents bars with convex surfaces attached to the bottom Aof said box, and adapted to runin the grooves of the wheels y upon the platform of the car.

lJ 3he letters orepresent pins aixed to the slats h, as'shown, and are intended for use in the dumping process, as hereinaler mentioned.

vThel letters f represent hooks attached to the upper surface of the platform, and operate in conjunction g with pins c, as stated hereafter.

Te'letters g represent bars with rounded upper suiaces attached to the top of the platform, and serve ast-racks for the `rollers a of the box.

The'letters n represent pinions adapted to 'operateA in the teeth of the ratchet-bars D.

shafts z, and operated by means of the hand-whecls I "lhe letters o represent cords aliixed to the'dnmping' box and the 'end pieces B, and serve to aid in preventing said box vfrom being. thrown from the car while the dumping'process is carried on.

,We usually plaoeftwo of these dumping-boxes otra hat, one: of which is moved to the `right side and the other to the left of said dat, as shown in the drawing. O ur apparatus is operated as follows, namely:

After beingr arranged upona-at, as above mentioned, the boxes are filled with gravel andthe cnrsmoved to the place of destination. 'lheoperator then turns the hand-wheels W, and the boxes are gradunlly moved outward until the pins c engage with the hooksf and the circular portionsof the ratchet-bars are passed over.the pinions. By this means the loads of the boxes are carefully and almost noiselesslydis# charged upon the rond-bed.' The box'es are then placed in their ('n'iginal positions 'and' are ready for other loads.

Weare aware that dumping-boxes have been attahed tocars, and we therefore do not4 claim, broadly, the invention of such attachment; but

Whatwe claim as our invention is- 1. The combination'c' the carrying and vdumping apparatus herein described with the bed or platiorm of'a dat, substantially as and for tue purpose specified. a

2. In a'dumping-box for railway cars, the ci cular ratchet-bars D, when constructed to operate substantially as and for the purpose mentioned.

3. The combination of the hars or trucksvande.A

with the rollers a and y, substantially as'and for the purposes specified'. In testimony that we claimthe above, we have .hereunto-subscribed our names in the presence ofV twol witnesses.
